简要总结
Pain after thyroid surgeries is considered to be of moderate intensity and short duration.
Patient may experience sore throat, odynophagia, burning sensation in the throat, nausea and vomiting which may be cause by the surgical procedure or due to endotracheal tube.
Usually, multimodal analgesia is tried for post operative patients. Non-steroidal anti-inflammatory drugs (NSAIDs) may not be effective for postoperative pain and opioids cause post operative nausea and vomiting.
So, recent studies concerning post thyroidectomy analgesia are focused on the efficacy of regional techniques.
Local anaesthetic wound infiltration (LWI), bilateral superficial cervical plexus block (BSCPB) and bilateral combined superficial and deep cervical plexus blocks are tried with variable results. All these methods share the same principal of cervical plexus sensory blockade at different levels.
LWI is a simple method of post operative pain management, because of its simplicity, safety and low cost. Its efficacy in decreasing post operative pain and analgesic consumption is demonstrated in many procedures like cholecystectomy, hysterectomy and hernia repair.
BSCPB is a popular regional anaesthesia used in thyroidectomy because of its feasibility and efficacy. Use of ultrasound guidance (US) facilitates the procedure by real-time visualisation of anatomical structures and needle movements and increases the chances of successful blockade while decreasing the rate of complications.
So, in this study, we are planning to compare the effectiveness of US guided BSCPB with that of LWI using bupivacaine dexamethasone mixture for post operative analgesia following thyroidectomies. In our study an effort has been made to compare analgesic efficacy and duration of analgesia of superficial cervical plexus block with that of local wound infiltration.
